Treatment of Impact and Airborne Noise transfer through Floors
Angel Step® is an acoustic underlay for carpet and solid timber or laminate floating floors. Angel Step’s construction combines a highly effective support and cushion for floating floors. It provides maximum performance for minimum thickness combining an impact and vibration damping and sound absorber with a decoupled noise barrier.
Angel Step® comprises an 8 mm layer of double needle punched polyester matting sandwiched between 4 kg/m² ‘visco-elastic’ polymer flexible noise barriers.
When laid over timber floors the first barrier in contact with the floor seals and damps the flooring substrate (T&G, ply, chipboard, marine ply). For concrete floors Angel Step® can be ordered without the bottom noise barrier.
The resilient polyester middle core layer absorbs impact energy and residual airborne noise from above and below, transforming wave vibrations into heat energy.
